Sorry for late reply.

So. I reinstall my Kubuntu completely to be sure that some install/purge
ppa/firmware/etc doesn't affect the system.

Now `uname -a` is:

Linux hpg6 4.4.0-34-generic #53-Ubuntu SMP Wed Jul 27 16:06:39 UTC 2016 x86_64
x86_64 x86_64 GNU/Linux


My Radeon card doesn't render anything (black window) but looks like it works.
When I start glxgears it shows FPS but window is black and stderr is full of
(see "4.4.0-34 DRI_PRIME=1 glxgears (stderr)" attachment).

The "UDV not responding..." error is also present (as usual).

I'm going to attach 4.4.0-34 files: dmesg, Xorg.0.log etc now

Tell me if I need to update my kernel to rc or another release.
